摘要

We studied the rigidity percolation (RP) model for aperiodic (quasi-crystal) lattices. The RP thresholds (for bond dilution) were obtained for several aperiodic lattices via computer simulation using the "pebble game" algorithm. It was found that the (two rhombi) Penrose lattice is always floppy in view of the RP model. The same was found for the Ammann's octagonal tiling and the Socolar's dodecagonal tiling. In order to impose the percolation transition we used so c. "ferro" modification of these aperiodic tilings. We studied as well the "pinwheel" tiling which has "infinitely-fold" orientational symmetry. The obtained estimates for the modified Penrose, Ammann and Socolar lattices are respectively: pcP=0.836±0.002p_{cP} =0.836\pm 0.002, pcA=0.769±0.002p_{cA} = 0.769\pm0.002, pcS=0.938±0.001p_{cS} = 0.938\pm0.001. The bond RP threshold of the pinwheel tiling was estimated to pc=0.69±0.01p_c = 0.69\pm0.01. It was found that these results are very close to the Maxwell (the mean-field like) approximation for them.
